Hey there Everybody,

I would like to introduce my bot, Eric the destructor. It is my first ever beetle weight robot and I intend to enter it in the university of west englands beetle weight competition in february. Ive only ever built a few ants and a couple of fleas, so hopefully my bot doesnt get to wrecked and goes home wearing the cone of shame!


This bot is a vertical spinner and its rudementary dimensions is 290mm width, 160mm length and 114mm height. Its approximate weight is 1.409kg minus screws, esc's or weapon belt.

Erics destructing gear:
drive - sk3 2122-2100KV brushless motors meshed to d25 500rpm gearboxes (i forget the gear ratio)
wheels - fingertech 63.5mm diameter
Weapon motor - propdrive 2836 1400kv brushless
1000mAh 11.1V lipo battery
Various thicknesses of HDPE
1.2mm grade 5 titanium plate

Do we have weapons?! The blade is made out of two single tooth aluminium discs. The discs are belt driven using a pully integrated between them and should weigh 279g.

Im pretty comfortable with the design with exception to the front plates. They are made out of 1.2mm titanium. Do you think that will be thick enough for beetle weight?
